25 Things You Didn’t Know About Se7en
10. The 'Gluttony' Victim Definitely Earned His Salary
For the gluttony scene, whole crates of cockroaches were poured onto actor Bob Mack, who was 480 pounds at the time and therefore could be considered to have been preparing for the role for most of his life.
Mack had no idea he’d have so many tiny scene partners until he saw the call sheet and noted the appearance of a ‘cockroach wrangler’. Apparently Brad Pitt flicked the insects off him between takes, and guards were placed in his ears and nose to stop the critters from crawling in.
Mack was obviously entirely naked for his first ever movie appearance, and has joked since that he was ‘Sharon Stoned’ in his debut role.
In the DVD commentary for the movie, David Fincher said that he felt terrible for Mack, who had to wear incredibly uncomfortable prosthetics for up to ten hours at a time before shooting would even begin - so he made the character well-endowed to compensate, giving the fibreglass dummy they used in the autopsy a large and shapely penis.
